Well, the funny thing about the cars from communist countries was that some of them, when designed in the 50-ies, were fairly modern at that time. But then they were produced unchanged for 30-40 years (e.g. Trabant, Syrena). In the late 60-ies Fiat sold license for their several models to those countries (to Poland it was Fiat 125 and 126). This moved the car making industry to modernity in the 70-ies. But then these cars also stayed unchanged until 90-ies.
On the picture you have:
- the dominant one (3 or 4 of them) are Polish first post war produced Warszawa M20 (produced until 1973!!); Soviet Union sold us the license for their M20 Pobieda (which was based, not necessarily through license) on one of the American cars from the 40-ies).
- there is black Volga, SU development
- Trabant (in the back)
- not sure what is the orange van (Barkas?)
- I am not sure if it is Fiat 500; I do not know what car is it - the white one
- I also do not know what car is the green one
